Filed May- 14, 1958 Patented Oct. 25, 1938 PATENT oF icE- SHOE MaynardH. Moore, Jr., Everett, Mass. Application May 14, 1938, Serial No.207,944 3 Claims. (or 36-12) "This invention relates to a type ofslipper in which a mid-soleusually of a form of cushioning material, isemployed between the'inner and outer soles and inwhich some provisionmust be made for covering'the edge of the mid-sole, so

' that it will present a finished, or ornamental appearance. 7

This has been accomplished by placing a binding of textile materialabout the edge of the mid-sole and securing it in position, the exposedsurface of the binding having an ornamental finish, usually ofPyroxylin.

As the edge of the mid-sole is flush with the edge of the outer sole,this binding is exposed to wear and in ordinary use'often becomesdefaced. For this, and other reasons a covering of thin leather isconsidered more desirable by some manufacturers and dealers.

Slippers of this type are almost'universally cemented, that is, thesoles are connected together and to the upper by an adhesive, butdifficulty has been encountered in securing a satisfactory adhesion tothe finished surface of either leather or imitationleather.

The object of my invention is to provide a slipper of the type aboveindicated, in which a leather or imitation leather finish may beprovided for the mid-sole and which is adapted to provide, withoutdifliculty, surfaces for adhesively connecting the mid-sole to both theouter and inner soles. I

I accomplish this object by providing amidsole which consists of tworelatively thinsole sections and providing a welt strip which ispreferably square in cross-section and which is covered with a strip ofleatheror imitation leather having a finished'surfa'ce and the edgeportions of which are secured between the mid-sole sections, theportions of the covering on the top and bottom sides of the welt striphaving the finished surface preliminarily removed; so that asatisfactory adhesion is secured to both the inner and outer soles.

For a more complete disclosure of my invention, reference is now made tothe following specification in connection with the accompanying drawingin which:

Fig. 1 is a perspective view of a finished slipper containing anembodiment oi. my invention.

Fig. 2 is a plan view, partly broken away of a mid-sole ready to beassembled with the other parts of the slipper.

Fig. 3 is a combined sectional and perspective view of a welt strip forconnecting the mid-sole sections.

Fig. 4 is a sectional view at line 4-4 of Fig. 2. Fig. 5 is a detailsectional view at line 5-5 of. a- Fig. 6' alongitudinal sectional viewof the heel portionof a finishedslipper. r i

As shown in the drawing the inner sole l0, onto which the upper I2. islasted, will, usually be of thin leather, or leather board stock, theedge portion of the upper being turned in beneath and adhesivelyconnected tothe under side of 10 inner sole, as usual. a r Accordingtomy invention I provide two midsole sections 14, iliwhich may be of anysuitable flexible sheet material of uniform thickness,such as thin cardboard, laminated paper, and ground cork and rubber composition, orcombinations of these materials. These mid-sole sections, while theycorrespond'inoutline to ,the innersole, as shown in Fig. 2, are somewhatsmallerthan both the inner andout-soles, for reasonswhich will appear. Ifurther provide a welt strip. l8, which ispreierably square in crosssection, andis preferably composed of rubber or rubber and ground porkcomposition, although other 'material' may. be employed, and ,said stripl8 isv covered with a. strip of leather, or imitation leather 20, whichis o! sufficient width to enclose the strip l8 completely and provideedge portions 20" which g overlap one another and are brought. into contact with each other at one side edge of the-strip l8, and secured inthis position by an interposed adhesive, or other suitable means,'asshown in Fig.3.

The overlapping edge portions of the strip 20 are then placed betweenthe edge portions of the mid-.solesections l4, l6 and extended entirely,about the same-and secured thereb'etween bystitches 24, so that thecovered welt strip It will be mounted on the edges of the mid-solesections, as shown in Figs. 2 and -4. The'meeting ends of the ,weltstrip are beveled, as indicated at ill, or they may be abutted. Thethickness of r the strip l8 and its covering 20 is made approxi-.matelyrequal to the combined thickness of the mid-sole sections when theedge portions of the covering strip have been placed therebetween, asshown in Fig. 4; and the outline otthe outer edge of the covering strip,when attached to the mid-sole sections as above described, is made tocorrespond as nearly exactly as possible'to the V outline of theoutersole 26, so that when the parts Before the covered welt strip isassembled with the mid-sole sections, the finished surface por tion ofthe covering strip directly above and beneath the strip l8 are buffedsufficiently to remove the finish, so that surfaces 28 are provided towhicha satisfactory adhesion may be secured. This buifing operation maybe readily performed automatically by feeding the strip between a pairof builing wheels, so that a pair of buffed stripes are formed thereon.When the parts as above described are assembled, the outersole isadhesively attached to the bottom side of the buifed surface 28 of thecovered welt, and the edge por tion of the upper, the finished surfaceof-which at the point of contact may also be bufied, is adhesivelyattached to the top side of the covered welt, as shown in Fig. 5.

These parts may also be attached by Littleway or Mackay" sewing, inwhich case, the stitches would be placed within'the welt stripapproximately-in the position of stitches 24,- and the outer sole andupper would preferably be adhesively attached to the bottom and topsideof the welt strip, as before described. Where this form of attachmentisemployed the welt strip may be preliminarily attached to the mid-so1esections. by stapling as the subsequent stitching would securelyhold-the mid-sole parts in posi tion? 1 With either'form of attachmentthe finished surface of the covering of the welt strip is exposedbetweenthe finished edge of the outer sole and the surface ofthe upper.

As the mid-sole is of'uniform thickness, a form ofwood heel thata'heel-lift section, ployed, is unnecessarmas shown in Fig. 6.

In addition to the advantages secured by having themid-sole sectionsfaced with leather, it will be noted that the finished surface on thewelt covering, which is removed to secure a strong adhesion, may beremoved at small expense before the welt and-mid-sole sections areassembled.

Also ;by having the mid-sole formed of two separatesections which areonly attached adjacent their edges, increased flexibility is secured, ascompared with that of a single sole of a thickness equal to the combinedthickness oiE-the two sections. a

Also the construction permits the employment of mid-sole sections ofdifierent materials, as for example, having one section of laminatedpaper and the other section of rubber and ground cork composition.
